Reading logs

Read the stream in time order

Open Logs → Console. Logs starts oldest-first because a debugging story is usually read as a sequence: setup, action, response, state change, failure. The time control can switch to newest-first when that better matches your investigation; the delta still describes the chronological gap.

Each row gives you:

• an absolute clock with millisecond precision;
• the level badge and inferred namespace;
• the rendered message, truncated only for the row layout;
• the delta from the previous visible event;
• a ×N badge when identical consecutive entries were merged.

The list is virtualized, so a long session does not require one DOM row for every retained entry.

Find the signal

The filter bar combines three ways to reduce noise:

• Search message text, namespace, stack text and serialized argument previews.
• Toggle one or more levels. The counts remain visible even when a level is turned off.
• Choose a namespace inferred from a prefix such as [Checkout] or Auth:.

Filters apply to the visible scope. After a Mark, the default view focuses on entries captured after the marker; clear or expand the earlier context when the setup matters too.

Expand a line

Long messages are shortened in the stream so neighboring events stay scannable. Rows with more to read show an expand affordance. Open as many rows as you need; expanding one does not close the others. The expanded value preserves line breaks and long text rather than forcing you to compare several clipped fragments.

Select the row when you want the full detail panel. That panel can contain structured arguments, an error stack, the absolute timestamp, repeat information and direct actions for Timeline and copying.

Copy the evidence

Use Copy log for a readable, timestamped version of the line plus its structured arguments and stack. Use Copy JSON when another tool needs the complete captured entry, including level, source, sequence and truncation metadata.

Copying is local to the browser session. NativeScope does not upload the entry or maintain a remote log archive.

Go from a row to Timeline

Press Timeline in the detail panel. NativeScope opens a scoped view centered on the exact timestamp of that entry, with the current row highlighted between its surrounding context. From there you can expand the earlier or later events, toggle tracks and open the log again in the Logs module. See Timeline for the full workflow.
